Notes on North Sea Basin Cainozoic echinoderms, Part 1. Miocene comasterid crinoids from central Limburg, the Netherlands

From strata assigned to the Breda Formation (Early to ?late Middle Miocene) penetrated in borehole 60B-122 at Pey-Echt (province of Limburg, the Netherlands), a single radial and an axillary primibrach (IBr2), both tentatively referred to comasterid crinoids, are recorded. In contrast to occurrences in central Europe (Paratethys and Mediterranean), crinoids appear to be extremely rare in the Miocene of the North Sea Basin. An overview of post-Paleocene comatulid crinoid records is added, with the emphasis on Europe.
